In order to understand and anticipate these changes, there is a crucial need for ... -

Durant, Joël M.; Hjermann, Dag Ø.; Stenseth, Nils Christian (ICES CM documents;2009/ P:08, Working paper, 2009)Climate influences populations through a variety of processes.

Llope, Marcos; Licandro, Priscilla; Chan, Kung-Sik; Stenseth, Nils Christian (Journal article; Peer reviewed, 2011-08-24)Traditionally, marine ecosystem structure was thought to be bottom-up controlled.
